SPIF rules need to be applied equally

by Mike Millian

I am going to begin this column by providing a bit of background on Safe, Productive and Infrastructure Friendly (SPIF) vehicles in Ontario. These vehicles are covered under the Highway Traffic Act regulation 413/05, Vehicle Weights and Dimensions. The SPIF regulations came into effect in four different phases that started in 2000 with phase 1, with the fourth and final phase being announced in 2010 and coming into law effective July 1, 2011.

The fourth phase covered straight trucks. The regulations were designed to provide safer vehicles for our highways, and to protect the infrastructure. The regulations lay out 31 different “prescribed combinations” that set out, among other things, allowed vehicle dimensions, including height, width, length, number of axles, type(s) of axles, weight allowed per axle and total gross vehicle weight. Laws were brought in through a grandfathered approach. For example, in the fourth and final phase, any truck manufactured prior to July 1, 2011, can operate under the pre-SPIF rules until Dec. 31, 2020, and with a permit, can extend this out further until the vehicle reaches 15 years of age. Any vehicle that was manufactured after July 1, 2011 was to comply with the rules effective immediately.

The SPIF rules did not come without their pain. In my previous job as a fleet manager, I dealt with the pains involved. Once the laws came into effect, we saw reductions in payloads for the newer spec’d SPIF vehicles when compared to the previous configurations we were using. There were also increased maintenance costs associated with self-steering axles. We suffered some initial performance issues with traction and steering control as weight distribution in some cases was less than ideal and weight was taken off the front steer, which is not good in winter driving conditions.

In short, I am acknowledging there were issues, however over time most of these issues were overcome by manufacturers and fleets. Loading of vehicles to ensure legal axle weights, especially vehicles that hauled bulk products, took some time to figure out, both for loaders and drivers. However, these pains were overcome once drivers and loaders gained experience in loading the new SPIF configurations. The gross vehicle weight losses were never fully regained, and a new business structure to account for this loss of revenue had to be found to stay competitive.

As the laws applied to all, we were all in the same boat. I am not saying we were happy, or that we even agreed with all the changes, but once it was clear things were not going to revert, we adjusted and did what was required. This came at a great cost and we, like many other players in the industry, paid our share to accomplish what was now legally required. Several PMTC members paid their dues and phased out old equipment and had to deal with the new reality. Several of these members operate essential services, such as delivery of home heating fuels, livestock feed and waste, to name just a few.

On Sept. 23, Ontario Minister of Transportation Steven Del Duca issued a letter to aggregate producers, haulers and other industry representatives, notifying them that the MTO would return to a phase 1 enforcement regime that had been in place until Aug. 1, 2016.

Effectively, this means the MTO will allow aggregate haulers to be overloaded on axle weights if they are within legal gross weights, are not beyond tire load limits and manufacturers’ gross axle weight ratings.

The MTO reached this decision, in part, because of strike actions that had been occurring at the Milton, Ont. weigh scales since Sept. 20. A segment of gravel haulers, mainly from the Toronto area, had been occupying the scale in protest of a return to strict enforcement of SPIF rules for the aggregate industry that had resumed on Aug. 1. In May of 2012, the MTO issued a similar notice, under then Transport Minister David Turnbull, indicating the MTO would not enforce a hard line on axle weights for the aggregate industry.

This was to be a short-term solution – which lasted four years and three months. The return to proper enforcement only lasted slightly more than six weeks, and then because of the strike action, phase 1 enforcement has been returned. In the view of the PMTC, the decision to not apply hard enforcement on axle weights to the aggregate industry either needs to be extended to all facets of the industry that are affected by these regulations – and there are many – or, the exemptions need to be removed in short order and the real issue dealt with. It has been over five years since the last phase came into effect, it is time we move forward and ensure the laws apply to all, fairly and equally.

  • As an operator of a SPIF dump truck, I have a few points to add to Mr. Millian’s article here.
    I do like my SPIF unit as far as the steering axle and self equalizing.
    BUT, control needs to be put back in the drivers hands as far as the raising and lowering of axles. My $4000.00 SPIF controller failed on month four after the truck was bought new. And I see many others going up and down the road with the axle up while loaded, and down empty because of a failure.
    Also, they do not steer in icy roads. While I have no issues on highway corners, my truck will often not make it around a 90* corner at an intersection in the city from a dead stop. It just pushes to the point of almost side swiping stopped vehicles. And I can verify that I have all my axles loaded equally at around 8600 KG on average, so it’s not improper loading. They do have a lift over-ride by using the four-way flashers under 60 KPH, but you have no time to do that in an emergency situation.
    They also do not work great off road. There needs to be an in-cab lift control, and just increase the fines if caught running loaded with it lifted.

    The other failure of the SPIF regulations is we recently looked in to purchasing a twin steer tandem-tandem. That way there is no computer controller for the lift to deal with, and no more dragging the lift axle tires sideways when off road in mud holes.
    But then we discovered, they greatly reduce your allowable gross if you pull a pony trailer with a twin steer.
    What sense does this make? The idea of SPIF was they wanted all you axles on the ground and equalized. So now, here you have the best set up, all axles on the ground, load equalized, better safer steering, and the same axle spreads as a SPIF lift truck…..and they penalize you??
    And yet, if you want to pull a pony/pup trailer, they want you to get a twin steer tri-drive, then that’s OK.
    It just doesn’t make any sense.

  • And as far as enforcing axle weights, the MTO does what they do best. Each enforcement officer seems to make up his own interpretation of the laws.
    Remember the last blockade back in the 1980’s, when they came up with the compromise of “we will not enforce axle weights on aggregate trucks, but we are taking 1500 KG off you allowable gross.”
    So what is happening still today…..guys are getting axle weight fines, despite being under their allowable gross WITH the 1500 already off.
    I once had an issue at an MTO scale where the officer wanted to charge me with my old non-SPIF dump truck. I was loaded with my 1500 off my allowable gross of 35,500 KG, plus I was a bit under that. The officer said I was 2500 KG over on my drives and maxed out on my steer and lift.
    How does that math work?? LOL. Needles to say, I got off with a “warning.” LOL.
    So then I thought I would test his knowledge. I asked how SPIF works. He had NO idea. Told me I still had to load 1500KG under my allowable.

  • The people that come up all these convoluted laws are a bunch of morons!

    They no doubt believe that the more complex they are directly equates to a job well done and justifies their own existence and pay cheque.

    I don’t understand half of them. The MOT understands less.

    In BC I was just fined at the Kamloops Inspection for having an over hang that was more then 25% of the value of the length from my king pin to the pivot point on my trail.


    Where do these morons come up with this shit?

    And the industry is suffering as a whole!

    Can’t get enough people interested in this career!

    It’s a joke, this career!

    And the worst decision of my life!

  • i agree with the first gentlemen in regards to the sliding and lack of steering in the turns and bad weather, but my real concern which i’ve seen happen is dump trucks blowing a front tire at highway speed and having zero control of the truck cuz the weight is then transferred on to the lift axle and clearly gonna pull you and steer in that direction to the side you blow the tire on and in to the wall or ditch and most likely flip and possibly become fatal. I’M SURE IF YOU’RE IN THE BUSINESS YOU’VE ALREADY SEEN OR KNOW SOME ONE THIS HAS HAPPEN TO.
